Is it that easy?
o Implementation of ABCDE bundle o Single center, pre/post study (n= 296)
o Lower delirium prevalence (62% vs 49%, p=0.02)
o Fewer days in delirium (33.3% vs 50%, p=0.003)
o More ventilator free days (21 vs 24 days, p=0.04)
o Increased mobilization (66% vs 48%, p=0.002)

Guideline Recommendations
o Recommend either daily sedation interruption or light target level of sedation be routinely used in mechanically ventilated ICU patients (+1B)
o Maintaining light levels of sedation in adult ICU patients is associated with improved clinical outcomes (B)
o Recommend that sedative medications be titrated to maintain a light rather than a deep level of sedation, unless clinically contraindicated (+1B)

Spontaneous Awakening and Breathing Trials
Daily awakenings trial (n=128)◦ Daily spontaneous awakening trial (SAT)

Target RASS Score Optimization
What? ◦ Relocated target RASS from sedative order admin instructions to separate
order
◦ Integrated into ICU rounds structure
Why? ◦ To ensure target RASS set for all patients
◦ To improve early recognition of (hypoactive) delirium
◦ To improve consistency between orders
◦ To increase visibility to clinicians

Guidelines: Treatment of Delirium
o There is no published evidence that treatment with haloperidol reduces the duration of delirium in adult ICU patients (No Evidence).
o Atypical antipsychotics may reduce the duration of delirium in adult ICU patients (C).
o We suggest that in adult ICU patients with delirium unrelated to alcohol or BZD withdrawal, IV infusions of dexmedetomidine rather than BZD infusions be administered for sedation to reduce the duration of delirium in these patients (+2B)

Summary: Drugs and Delirium
Less is more◦ Minimize deliriogenic medications
◦ Choose appropriate sedation (treat the patient!)
Antipsychotics◦ Limited evidence, risk for ADE
◦ Long term impact and costs unknown
◦ May reduce duration of delirium
Melatonin agonists◦ May be effective for prevention

Early Mobilization
Guidelines: Recommend performing early mobilization of adult ICU patients whenever feasible to reduce the incidence and duration of delirium (+1B)
Requires optimizing ICU environment (and culture) for mobility◦ Pain and sedation management
◦ Sleep promotion

Early Rehabilitation and Delirium
Schweickert et al, 2009◦ Progressive algorithm ~1.5 days post-intubation
◦ Shorter duration of ICU delirium (2 vs. 4 days, p=0.03) with similar sedative administration/SAT
Needham et al, 2010◦ Reduced benzodiazepines (BZD)
◦ Days with bzd (25% vs. 50%, p=0.002)
◦ Total daily dose of bzd (47 mg vs. 15 mg, p=NS)
◦ Reduced delirium (21% vs. 53%, p=0.003)
